He said he would get even with those who wronged him in an event to reclaim his good name.

"You're going to see what a whistleblower can do when you take everything from him especially his NAME!!!" he wrote. "You have awoken a sleeping giant."

Chief Charlie Beck, who initially dismissed the allegations in Dorner's rant, said he would reopen the investigation into his firing - not to appease the ex-officer, but to restore confidence in the black community, which long had a fractured relationship with police that has improved in recent years.

One of the targets listed in the manifesto was former LAPD Capt. Randal Quan, who represented Dorner before the disciplinary board. Dorner claimed he put the interests of the department above his.

The first victims were Quan's daughter, Monica Quan, 28, a college basketball coach, and her fiance, Keith Lawrence, 27, who were shot multiple times in their car in a parking garage near their condo.

Dorner served in the Navy, earning a rifle marksman ribbon and pistol expert medal. He was assigned to a naval undersea warfare unit and various aviation training units, according to military records. He took leave from the LAPD for a six-month deployment to Bahrain in 2006 and 2007.
